Abstract: PURPOSE: To enable to actuate a control element with a small control force, by providing a variable control element for controlling the displacement from its minimum to miximum flow rate, and keeping said variable control element at its neutral position in an operational range in which any control is required for the input revolutional speed.  
     CONSTITUTION: In a hydraulic pump shown in the drawing, a cylinder block 7 is mounted on an input shaft 5 which is supported in housing 1 in freely rotatable manner. In the blovk 7, a multiplicity of pistons 8 are placed in respective piston chambers 7a in freely slidable manner, and these pistons 8 are held in contact with swash plate 12 serving as variable control element by the intermediary of shoes 11. On the other hand, swash plate 12 is connected to actuator 17 via links 14W16, so that displacement of the pump is rendered variable by controlling the displacement of swash plate 12 through operation of actuator 17. Further, a retainer 19 is connected operatively to swash plate 12 for keeping the swash plate 12 at its neutral position a in an operational region where trunnion moment is acted in negative mode. The retainer 19 is further connected with an operational signalling means 20 which releases retainer 19 when the input revolutional speed becomes higher than a predetermined value.

Title: Buckling detection method in continuous heat treatment furnace
Inventor: ONAKA MINORU
IPC: G01B11/24
Filed: 1992-02-14
Abstract: PURPOSE:To provide means for measuring the buckling of a steel plate running through a continuous heat treatment furnace accurately. CONSTITUTION:A steel plate 1 located at a contact part with a steel plate carrying roll 2 is irradiated from the side thereof with a laser beam 8 in the breadthwise direction and scanned in the direction of the thickness. In this regard, the temperature of a plate heater 12 disposed above the steel plate while opposing thereto is controlled at a level substantially equal to that of the steel plate thus controlling the ambient temperature gradient between the steel plate and the plate heater. A scanning laser beam passing between the steel plate and the plate heater is received by an optical detector 5 and the buckling is decided based on the difference between the normal interval and the light receiving interval. Since the temperature gradient above the steel plate through which the laser passes can be suppressed along with the variation thereof, the buckling can be detected accurately.
